STOPPER.FOR HOT-WATER BOTTLES.

osaese.

To all whom it may concern:

Be it known that 1, CHARLES F. Scrum, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Stoppers for Hot-Water Bottles, of which the following is a specification.

This invention relates to stoppers for hot water bottles and the object of the invention is to provide an efiective stopper which will be cheap to manufacture and convenient in use.

The stopper is so constructed that there is the maximum room for the passage of the Water, and the socket member and the stopper so shaped that the sealing gasket is closed practically on all sides and can-.

not be jammed out of shape or position, and a stopper retaining device is provided which will not contract when pulled and hence cannot be accidentally pulled out of the bottle.

The invention consists of the stopper hereinafter described and claimed.

Inthe drawings accompanying and forming part hereof: Figure 1 is a vertical section of part of a water bottle having my improved stopper shown in connection therewith. Fig. 2 is a side elevation of the stopper, partly in section. Fig. 3 is a vertical sectionv of the screw threaded socket mcnr ber. Fig. 4 shows the retaining device before and after its insertion into the bottle.

Referring now to the details of the drawings by numerals: 1 indicates the funnel shaped neck of a hot water bottleof the usual or any desirable form, although it may be here stated that my invention may be used in connection with other bottles if desired. \Vithin the neck of the bottle is vulcanized a screw threaded socket member 2 and while this member may be of the ordinary form, I prefer to make it of the form shown particularly in my drawings from which it will be seen that instead of having an annular flange projecting inwardly at its lower edge, my socket member 2 has the 4 same interior diameter throughout its entire threaded portion and has no annular flange at its bottom. This makes a desirable construction for the reason that when the stopper is removed, the bottle is completely open, thus providing the entire space for the flow Specification of Letters Patent.

of water. All who have hadexpericnce with filling hot water bottles have realized the disadvantages of the old form of socket members and have experienced the inconvenience of having the flange at the bottom of the socket member act as a trap whereby the hot water would be splashed back over the hands. By providing a free entrance for the water, this disadvantage is entirely overcome. My-socket member is also provided with a plurality of threads. In the form shown in the drawings it will be noticed that there are double threads both within the interior of the socket member and upon the stopper itself and this makes it possible to screw the stopper home with half the turning necessary when a single thread is used. The socket member 2 is furthermore flanged outwalrdly at an angle at its upper end and the material is bent back upon itself as illustrated at 3-4, to give greater thickness and rigidity. I call attention. to the fact that the outward flaringof the socket member not only has the advantage of coacting with the gasket of the stopper in a manner hereinafter pointed out but also increases the size of the opening at the upper end of the socket member so that the outwardly flanged portion acts somewhat as a funnel and is formed on the same angle as the funnel shaped mouth 1 of the water bottle itself.

My stopper is designated by the numeral 10 and is formed of the shape illustrated particularly in Fig. 2. As there shown it is provided with a handle 12 which may be of any desired construction and under this handle is an (Wei-hanging flanged portion 14 underneath which is provided an annular groove 16 which. when the stopper is inserted in the screw thread socket memher 2, is exactly 'Hll'illlGl with the flanges of the outwardly anged portion of the said socket member. This flange 16 provides a seat for a gasket 18, the scat int-losing the gasket on three of its sides as clearly illustrated in the drawings. The stopper below the seat 16 is provided with two threads 20 and 21, and below the threaded portion is a part 23 of slightly smaller diameter than the threaded portion. The reason for making this part 23 of smaller diameter than the threaded portion is that when the stopper is inserted in the bottle, the smaller portion 23 will readily fit within the threaded por bodiment, is a piece of sheet brass formed first of the shape shown at the left hand part of Fig. 4 so that said member will readily enter the neck of the'bottle, passing through the socket member 2. After the said memher is within the bottle, it is flattened out by a suitable tool (not shown) to the shape shown in Fig. 1 and at the right hand of Fig. 4:. Thus I have provided a retaining device for a stopper which takes up aminimum amount of space and yet is so rigid that it is impossible for the retaining device to be bent and pulled out of the socket by an undue pulling on the stopper 10. I attach considerable importance to this retaining device and believe it to be much superior to those heretofore proposed.

1 am aware that retaining devices are old, that spring wire rings have been used for this purpose, that elastic rubber rings have also been used and that wire bent into a triangular shaped bottom has also been used; but all of these'have the disadvantage that my device overcomes in that mine provides an absolutely stiff, not resilient, retaining device larger in diameter than the socket through which the chain passes, the size and stifiness of the retaining device preventing it from being contracted or otherwise pulled out of the bottle.

I also desire to call particular attention to the fact that when the stopper 10, with its gasket 18 contained within its groove 16 is screwed home within the socket member 2,,the line of pressure upon the gasket is directly at right angles to the bottom of the gasket seat 16, and inasmuch as the gasket 1s surrounded on three of its sides by said gasket seat, and as the pressure is directly flared or funnel shaped neck, a screw threaded socket member secured therein having an outwardly flared portion at its upper end formed substantially at the sameangle as the said funnel shaped neck of the bottle, a stopper arranged to screw in said screw threaded socket member having an annular seat for a gasket, and a gasket of flat form rectangular in cross section, located in said seat, said seat and said gasketbeing located substantially parallel with the outwardlythreaded socket member and having a seatfor a gasket, and a gasket located in the seat in said stopper, said seat and said gas ket being substantially parallel to the outwardly flared portion of said socket member, and the seat having a shoulder substantially under one edge of the gasket, whereby when the stopper is unscrewed the gasket, owing to its being inclosed in the stopper and having the shoulder of the seat under one of its edges, will be positively moved out of contact with theoutwardly flared wall of the socket member, substantially as described.

3. The combination. of a bottle having a screw threaded neck, astopper arranged to be screwed within said neck, and a retaining device hanging within the bottle from the inner end of the stopper, said retaining device being formed of a rigid piece of metal bent before its insertion through the neck of the bottle toa size to pass through said neck and after its insertion in the bottle bent to a size too large to pass through the bottle neck, substantially as described.

lln testimony whereof I affix my signature in presence of two witnesses.
